Description
Technical field
The present invention relates to a kind of thermoplastic resin composition who comprises with the P contained compound of polymer form, by the molded plastics molded products of said composition and a kind ofly be used to prepare method with the P contained compound of polymer form.
Background technology
Thermoplastic resin is because their good processing characteristicies and mechanical property have been used for the electronic goods of part.Its range of application increases severely along with the recent development of various functional additives.Yet many thermoplastic resins are inflammable and fire had atomic little resistance.Therefore, plastics can burn and in propagation of flame, work through the burning things which may cause a fire disaster of outside easily.From identical consideration, many countries (like the U.S., Japan and European Union) require fluoropolymer resin to meet some fire-protection standard, to guarantee the anti-security of catching fire of electronic goods.
A kind of domestic method that is used for giving the polymkeric substance flame retardant resistance is that fire retardant is joined polymkeric substance and forms blend.These additive flame retardants can be categorized as halogen-containing flame retardant, phosphonium flame retardant, contain nitrogen combustion inhibitor, (silicone-containing) fire retardant that contains silicone resin and contain inorganic combustion inhibitor, and this depends on its component.Among these, halogen contained compound and inorganic-containing compound (blend) are often as fire retardant.
When using the combination of halogen contained compound and antimony containing compounds, flame retardant resistance can be improved with low cost.Therefore, this combination has been used for various resins (like acrylonitrile-butadiene-styrene (ABS) or ABS resin, PS or PS resin, polybutylene terephthalate (polybutylene terephthalate) or PBT resin, polyethylene terephthalate or PET resin, epoxy resin etc.) are used for electronic product with production case material.Yet, can have the environmental problem relevant, and it uses and to be limited the use of instruction (Restriction of Hazardous Substances) by the hazardous substance that comes into force in July, 2006 and (RoHS) limit with halogen contained compound.Therefore, some halogen-containing flame retardants that are called as " ten (deca) " are stopped using, and its consumption significantly reduces.Also therefore, give the interest increase of the method for flame retardant resistance recently for not using halogen contained compound.
Phosphonium flame retardant has been used as the surrogate of halogen contained compound, to give the thermoplastic resin flame retardant resistance.Phosphonium flame retardant can provide good flame retardant property with solid phase, especially in containing the plastics of a large amount of oxygen.Phosphonium flame retardant can be categorized as phosphate class, phosphine oxide class, phosphite/ester class, phosphonate/ester class etc.; And can obtain flame retardant resistance with char-forming agent (carbon forms agent, char-forming agents) (like polycarbonate or poly (phenylene ether) resin) combination.Typically, unit molecule P contained compound such as triphenylphosphate or Resorcinol bis-phenol SULPHOSUCCINIC ACID ESTER (resorcinol bisphenol phosphate) are as such P contained compound.When using the unit molecule phosphonium flame retardant, can easily obtain flame retardant resistance.Yet because these compounds have lower molecular weight, they can volatilize under the molded typical high molding temperature of plastics, and then outward appearance that can the deterioration plastics.And when the plastics that use after molded, the unit molecule fire retardant can be discharged, and this can cause environmental problem.Therefore, in order to solve above mentioned problem, has the interest of increase for polyphosphonates with the phosphonium flame retardant of polymer form.When the polyphosphonates with polymer form is used as flame retardant additives, compare with present unit molecule phosphonium flame retardant, can keep good flame retardant resistance and mechanical property, and non-volatile during plastics are molded.In addition, because it and many existing fluoropolymer resins have high-compatibility, compare with the unit molecule fire retardant, it can be easy to use so that transparent material to be provided.And because after molded, can have low extractability (extractability) with the polyphosphonates of polymer form, its use can reduce to minimum with environmental problem.
